The output of a 2-input multiplexer is connected back to one of its inputs as shown in the figure. Match the functional equivalence of this circuit to one of the following options.
- D Flip-flop
- D Latch
- Half-adder
- Demultiplexer
Correct answer: D Latch
Solution
The circuit behaves like a D latch because it holds the value of the input when the control signal is active, allowing it to store data based on the input while being transparent to changes when the control signal is inactive.
